the stem or remove spacers.
After making adjustments to the stem, check that the stem is tightened by trying to turn the handlebars left
and right while you hold the front wheel between your legs.
for your safety, adjust your handlebars so that you can easily access the brake levers and the shifters.
for mountain bikes: the shifters should be positioned in the prolongation of your forearms when you are in
riding position on the bike.
for road bikes: In general, the lower part of the handlebars should be horizontal.

one of two types of headsets: classic (when the front fork, which has screw threads, is secured by a locknut),
or threadless (when the front fork is clamped by the handlebar stem itself and the play can be adjusted by
tightening the top cap).

damage to your bike.
Here are two simple tests to perform before each ride:
TEST 1 – while applying the front brake, try to move the bike forwards and backwards. You will notice right away
if there is movement of the steer tube in the headset.
TEST 2 – You can also hold the handlebars and top tube loosely and gently bounce the front wheel on a concrete
surface (the tire must be inflated). You will hear a hollow vibration if there is any play (ignore the sounds of
vibrating cables, etc.).
